Miniature device offering long-life switching is more reliable, lower power alternative to mechanical relays.

-- Toshiba Electronics Europe (TEE) has launched a semiconductor photorelay (MOSFET output photocoupler*) that combines a very low turn-on current with an ultra-compact form factor. The new TLP175A is particularly suitable for designs that demand high-reliability switching and improved efficiency while saving board space.

Toshiba’s new photorelay provides a smaller, more reliable, longer life and lower power alternative to mechanical relays. Target applications will include security systems, factory automation equipment, utility meters and instrumentation. Minimum creepage and clearance distances of 5.0mm and an internal isolation thickness of 0.4mm (min) contribute to a minimum isolation voltage rated at 3750Vrms.

The photorelay’s miniature 4-pin SO6 package incorporates an infrared LED that is optically coupled to a photo MOSFET. Package dimensions are just 7.0mm x 3.7mm x 2.1mm. A 1mA current is all that is required to trigger the LED and turn the photorelay on.

Featuring a normally open (1-Form-A) configuration, the TLP175A has an OFF-state output terminal voltage of 60V and a maximum ON-state current of 100mA. Performance is guaranteed for operating temperatures between -40°C and 85°C.
